When I was younger, I used to lie all the time, mostly because I was afraid of what would happen if my parents or brother or friends would think of the truth. But as it went on it got worse I became to love lying it made me feel better. I remember one time I was home alone when all my parents and family went out to go see a movie. I felt stupid because I was home not having fun and they were. So when they came home I made up a lie to make myself feel better. Told them someone tried to brake in, for some reason it made me feel better. After that lying just became a ritual for me, couldn't stop sometimes I lied so much I almost believe the lies. But 1 year ago I got out of it, it got to me, my conscience, if you may. It ate at me, drove me crazy, I didn't like lying anymore. So after that I just got over it, practiced not lying allot. Forced myself to not lie when I no I really wanted to.
Now I don't know if this is some-what like what your going through but if it's any ease, you can stop, you can get over it. I guess I went the hard way by forcing myself not to lie. Maybe theres other ways you can get over it, (medication if there is such a thing for this). Just one thing I can remember that help me is to get in a routine of not lying, force yourself, get you mind off of it. Other then that it's up to you..
